Replacing the rings on my 2000. The top pic shows the originals which butted together (I think) and were held in place by the convuluted ring in the groove. The second pic shows the AE NOS replacements. No convuluted ring and I'm assuming they somehow are supposed to interlock together but I've been unable to do so without risk of distorting them. Anyone have any ideas? Should I be reusing the convuluted rings and butting them together? Any info appreciated.
